Monitor and control your GivEnergy solar & battery system from your own computer.
No cloud account needed. Your data stays on your network.
Windows users can also get Home Energy Manager from the Microsoft Store.
Solar generation, battery charge, grid import/export, and home consumption — updating live every few seconds.
Animated visual showing where your power is flowing right now — solar, battery, home, grid.
Cell voltages, temperatures, and health for every battery module. Cold battery warnings included.
Up to 10 charge and 10 discharge time slots. Switch between Eco, Timed Discharge, and Pause modes.
Force Charge and Force Discharge buttons for instant control. Click to start, click again to stop.
Open Consumption Report from the Power page for charts, summary tables, cost breakdowns, and Print / save as PDF. History exports CSV only.
Charts from 15 minutes to 7 days. Enter your tariffs to see real-time cost estimates, and export History data to CSV.
Enter your three cheap-rate windows and the app automatically charges your battery during each one.
Set price thresholds and the app charges when prices are low, discharges when high, with a live 24-hour forecast.
Protects your battery from cold by automatically charging it from the grid when the temperature drops.
Voltage, current, and power for each solar string. Supports dual-string systems.
External meter readings with per-phase data and CT clamp status card.
Works as a headless server on a Raspberry Pi. Access from your phone via Tailscale — no cloud needed.
Get alerted when battery temperature, SOC, or solar exceeds thresholds — via Telegram, ntfy, or Pushover push notifications. Send /status, /today, or /report in your Telegram chat for a live snapshot, today's cost summary, or yesterday's full consumption report.
Home Energy Manager supports every known GivEnergy model.
